摘要
研究鱼眼图像的拼接算法,实现利用两幅鱼眼图像生成球面虚拟空间,然后探讨基于球面虚拟图的多视点漫游问题,利用反投影模板技术有效地提高全景图浏览的速度,采用缩放的方法改进了行进间的浏览效果,从而提高虚拟漫游的沉浸感,具有一定的实用意义。
Spherical virtual space modeling using fisheye image is accomplished based on fisheye image mosaics,and then multi-viewpoint navigation is discussed.Test proves that virtual browsing speed can be improved using re-projection technology and browsing effect can be improved using zooming technology,thus immerse sense in virtual environment is enhanced,and good result is gained.
